Remember that children's book, Harold and the Purple Crayon? This is essentially that book made into a game, minus the toddler, and plus a lot of physics elements. Crayon Physics Deluxe has been making fans on the PC and iOS for years, and yesterday it finally hit the Play Store (after slumming it on the Galaxy Note 10.1 for a few months). The objective is to roll a 2D ball over a star, but that's like saying the point of baseball is to hit a ball with a stick: There's a lot more to it.

We all have a deep-seated desire to smash things – a love of destruction, if you will. Don't bother denying it. Well, there are plenty of things to destroy in Catapult King, a game that made quite an impact on iOS. This is a physics game that invites you to knock down all manner of structures with a magical catapult.

You can think of Catapult King as a more advanced version of Crush the Castle.

What happens in the unlikely event that a shark falls in love with a space dog? Clearly, the shark will follow the dog into space, because blast your logic! If Astro Shark is going to be reunited with Laika the space dog, he's going to have to dodge some missiles and travel the stars. Romantic, no?

Astro Shark is a physics-fueled adventure game that involves hopping from one planet to the next to gain speed and evade missiles.

You know how it is. You're just trying to do your thing, and you keep getting attacked by cubes. So annoying, right? In the world of Cubes vs. Spheres you can show those dumb 3D squares who's boss by flinging powerful spherical projectiles at them. The game comes packed with 6 spheres, 40 levels, 37 achievements, and thousands upon thousands of cubes.

Cubes vs. Spheres has controls for the accelerometer or touchscreen – whichever you prefer.

Do you like physics games? I sure do. Puddle THD happens to be a great game in this category if you happen to have a Tegra 3 device. The puzzle-centric fluid simulator is typically available on the Play Store for $5, but today the app has gone on sale for a measly $0.99 to celebrate its first whole year on the market. Not bad!

To get an idea of what this game is like you can either watch the video above or rely on my words.

Whatever you have planned this evening, I suggest you clear some time in your busy schedule to play a little Tupsu. What is Tupsu? It's a physics-based puzzler that you can play on your Android device, and you can leave the (Google) wallet in your (virtual) pocket – Tupsu is totally free.

Tupsu (the thing, not the game) is a furry little ball with sticky eyes on long flexible stalks.

How do you follow up an earth-shattering hit like Angry Birds? Not with Amazing Alex, Rovio's first property to branch out of their only previous IP. The game currently sits with only a tiny fraction of the downloads of Angry Birds, even on the free version. So with the third go-round, they've gone back to create a spinoff featuring the antagonists of the aggravated avians: Bad Piggies. The new game is a combination of the previous two, combining the simple physics-based goals of Angry Birds and the contraption building of Amazing Alex.

Space-inspired physics games have been given a boost thanks to Angry Birds Space. If you're looking for something with a little more drama and a little less pig, then New Orbit might be right down your gravity well. The 99¢ game from rookie developer Blackish combines Asteroids-style navigation, gravity-driven physics and an ambitious if not overly promising story. On that note, the full title is "NEW ORBIT: Episode 1," so there's probably more on the table.

If you've got a device powered by a Nvidia Tegra system-on-a-chip, a solid internet connection, and one US dollar, you're in for some fun. The price on physics-based puzzler Demolition Inc. has dropped from $3.99 to just $0.99. That's a heck of a deal.

In Demolition Inc., you take on the roll of Mike, the alien demolition truck driver. Some pesky human cities are in the way, and you've got a work order that says to knock them down.

You might want to clear your schedule for a few weeks in May because that's when the game Rigonauts will be appearing in the Play Store. An early version of Rigonauts from Engient took second prize in Activision's Independent Games Competition last year, and now an updated version with improved graphics and gameplay is on the way to Android, iOS, and PC. This is a physics-based fighting game with a healthy dose of strategy, and that's not something that comes along everyday.
